Linphone:Armbian(Debian Buster)+Orange Pi ビルド・インストール

Linphoneソースからのビルドインストール

デスクトップバージョンv3.12(GUI無し)をビルド・インストールします。
linphone-nogtkパッケージが公式に配布されていますが、ソースからのビルド・インストールをお勧めします。

https://wiki.linphone.org/xwiki/wiki/public/view/Linphone/Linphone%20and%20Raspberry%20Pi/

インストール環境

  • OrangePi PC
  • Ubuntu Bionic with Armbian Linux 4.19.62-sunxi

開発環境・関連ライブラリのインストール

$ sudo apt-get install cmake automake autoconf libtool intltool yasm libasound2-dev libpulse-dev libv4l-dev nasm git libglew-dev

Githubからソースコードダウンロード

$ git clone git://git.linphone.org/linphone-desktop.git --recursive

Linphoneデータベース用ディレクトリ作成

$ mkdir /home/user_dir/.local/share/linphone
$ chmod -R 775 /home/user_dir/.local/share/linphone

Pythonコードによるビルド環境の構築

$ cd linphone-desktop
$ ./prepare.py no-ui -DENABLE_OPENH264=ON -DENABLE_WEBRTC_AEC=OFF -DENA BLE_UNIT_TESTS=OFF -DENABLE_MKV=OFF -DENABLE_FFMPEG=ON -DENABLE_CXX_WRAPPER=OFF -DENABLE_NON_FREE_CODECS=ON -DENABLE_VCARD=OFF -DENABLE_BV16=OFF -DENABLE_V4L=OFF

makeビルド

$ make -j4

ビルド終了後、ビルドパッケージ no-ui/opt ディレクトリにコピーしてパスを追加します。

$ sudo cp -r /home/user_dir/linphone-desktop/OUTPUT/no-ui /opt/
$ export PATH=$PATH:/opt/no-ui/bin

Linphone起動

Linphoneを起動してユーザ認証などの環境設定を行います。ユーザ登録は下記サイトで行って下さい。
https://www.linphone.org/freesip/home

$ linphonec
linphonec> proxy add
.....
linphone>quit

Linphone終了後、設定ファイル.linphonercが起動ディレクトリに作成されるので、インストール環境に合わせて項目を追加・修正します。上記コンソール内のLinphoneコマンドは下記を参照して下さい。

Linphone起動スクリプトによる自動起動

$ sudo pico /etc/init.d/linphonecsh

    #!/bin/sh
    ### BEGIN INIT INFO
    # Provides:          linphone
    # Required-Start:    $remote_fs $syslog
    # Required-Stop:     $remote_fs $syslog
    # Default-Start:     2 3 4 5
    # Default-Stop:      0 1 6
    # Short-Description: Starts Linphone daemon.
    # Description:       Linphone is used to call and receive message on VoIP System.
    ### END INIT INFO
    export PATH=$PATH:/opt/no-ui/bin
    sudo -H -u user linphonecsh init -c /home/user_dir/.linphonerc

実行権の付与

$ sudo chmod +x /etc/init.d/linphonecsh

起動時スクリプトの登録

$ sudo update-rc.d linphonecsh defaults

"$sudo -H -u user linphonecsh …" コマンド実行エラー対応

rootによる指定パス以外のコマンド実行が無効となっているため、/opt/no-ui/bin内のコマンドを実行できません。以下secure_path/opt/no-ui/bin を追加します。

$ sudo visudo
Defaults        secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin:/opt/no-ui/bin"

システムを再起動してLinphoneが起動しているかどうかhtopコマンドなどで確認して下さい。

ターミナルからのLinphoneコール関連コマンド

応答

$ sudo -H -u user linphonecsh generic “answer”

終了

$ sudo -H -u user linphonecsh generic “terminate”

ダイヤル

$ sudo -H -u user linphonecsh dial “sip:user001@sip.linphone.org

tls接続する場合の設定例:".linphonerc"

デフォルトでTLSポートを指定する必要があるようです。

アップデートに伴う再ビルド・インストール

Armbian 21.02.3 Buster with Linux 5.10.21-sunxi
Linphoneビルド・インストールバージョン: 4.5.0

githubのlinphone-sdkソースからプラットホームを指定することで、直接linphone, flexisip等のビルドが出来るようになったようです。

事前準備
上記最新ArmbianがDebian Busterベースなので、linphone-sdk/docker_filesを参照してビルドに必要なパッケージを事前にインストール

BUG: liblinphone won’t initialize correctly if the data directory (for persistent storage) is not created. To workaround do:
事前に以下ディレクトリを作成して下さい。
$ mkdir -p ~/.local/share/linphone

bc-dev-debian10

開発ツールのインストール

$ sudo apt-get install -y alien at autoconf bison ccache clang cmake doxygen elfutils g++ gdb git graphviz intltool libtool lsb-release make nasm ninja-build openssh-client patch yasm

Linphone開発ツール依存パッケージのインストール

$ sudo apt-get install -y libasound2-dev libavcodec-dev libavutil-dev libbsd-dev libegl1-mesa-dev libglew-dev libgsm1-dev libmariadbclient-dev libmbedtls-dev libopus-dev libpq-dev libpulse-dev libspeex-dev libspeexdsp-dev libsqlite3-dev libsrtp2-dev libssl-dev libswscale-dev libturbojpeg0-dev libv4l-dev libvpx-dev libxerces-c-dev libxml2-dev libxv-dev xsdcxx

linphone-sdkソースのダウンロード

GCC ARM Options

https://gcc.gnu.org/onlinedocs/gcc/ARM-Options.html

-mfpu=name

This specifies what floating-point hardware (or hardware emulation) is available on the target. Permissible names are: ‘auto’, ‘vfpv2’, ‘vfpv3’, ‘vfpv3-fp16’, ‘vfpv3-d16’, ‘vfpv3-d16-fp16’, ‘vfpv3xd’, ‘vfpv3xd-fp16’, ‘neon-vfpv3’, ‘neon-fp16’, ‘vfpv4’, ‘vfpv4-d16’, ‘fpv4-sp-d16’, ‘neon-vfpv4’, ‘fpv5-d16’, ‘fpv5-sp-d16’, ‘fp-armv8’, ‘neon-fp-armv8’ and ‘crypto-neon-fp-armv8’. Note that ‘neon’ is an alias for ‘neon-vfpv3’ and ‘vfp’ is an alias for ‘vfpv2’.

The setting ‘auto’ is the default and is special. It causes the compiler to select the floating-point and Advanced SIMD instructions based on the settings of -mcpu and -march.

If the selected floating-point hardware includes the NEON extension (e.g. -mfpu=neon), note that floating-point operations are not generated by GCC’s auto-vectorization pass unless -funsafe-math-optimizations is also specified. This is because NEON hardware does not fully implement the IEEE 754 standard for floating-point arithmetic (in particular denormal values are treated as zero), so the use of NEON instructions may lead to a loss of precision.

You can also set the fpu name at function level by using the target("fpu=") function attributes (see ARM Function Attributes) or pragmas (see Function Specific Option Pragmas).
